`Specifieation of LettersiPatent No. 8,068, dated April 29, 1851.

To all LU/1.0m 'itmay concern:

Be it known that I, LEANDER W. BOYN- ToN, of South Coventry, in the county of Tolland andState of Connecticut, have invented anew and useful Improvement in the Method of Inserting Flock `.into the i VVoolen Web for the Manufacturing of `Felt e cylindrical brushes, the bands, pulleys, end-` Cloth, Hat-Bodies, &c.; and I `do hereby declare that the following is a full, clear, and exact description of the character, con struction, and operation of the same, refer ence being hadto the accompaiiyingdrawings, which make a partof this specification, in which* e i e Figure l is as perspectiveview of the machine for preparing the flock to be inserted, or incorporated, showing two of the three less apron, &c. Fig. 2 is a perspectivevview of the opposite sidejof the same, complete, and ready for `use, showing the crank, or power by which it is worked, the pulley and band by which the endless apron is moved, the case in which the brushes are inclosed, &c.

My improvement consists in preparing and introducing the: flock onto the web ofl wool after it comes from the carding machine, (as while it Iis on an endless apron,) without passing the iiock through the carding machine, by which means I am able to introduce any desired quantity of flock into any desired portion of the texture ofthe felting, as all in the central port-ion, between the two surfaces, or all on one side, or sur- 1 f ,the usual way, and is propelledbythe band face, or equally, `or uiieqi'ially, throughout the whole texture, as convenience, usefulness, &c., may direct, and to use the very shortest flock with equal facility and ad-.g

vantage with `the longest that is ever found,

and in the construction and operation `of the machine forpreparingtlie flock for insertion, and depositing it on the web of wool after the web comes from the doer and is passing along on the endless apron or other- This endless apron, B, is represented in the drawings as attached tothe preparing machine, (hereafter to be described,) merely to `show its proper position in `relation to that` machine, but when used it must be attachedV to thecarding` machine, under, and,` extend-` ing from, the doffer, and the preparing inachine, represented in the drawings, must be lplaced above it in a convenient position,

which may be in an upper room, if found more convenient, in any case, having a spout, or conductor, (A,) extending down nearly to the endless apron, (B,)` or: theweb as it Y is passing from the carding machine.

I make the machine for `preparing the flock of asuitable frame, C, C, &c., `of a convenient size and shape, suited to the `quantity, and kind, of work intended to be performed by it.

In, or near, one end of this frame I fit two, three, i (or inore,) cylindrical brushes, I), and E, on, or nearly the saine` elevation, and` the other below them,

tas shown bythe pulley F, Fig. 1,(and the end ofthe arbor, at F, Fig. `2. These cylinzdrical brushes are caused to revolve in the `directions indicated by therdarts, by means of theband, G, G, Fig. l, orby any other convenientmeans or appropriately arranged gearing. H, and I, Fig. l, are live pulleys merely for the purpose `olf direct-ing `the band. In the other part ofthe frame, C, C, &c., I fit an endless apron, K, Figs. l and 2,

oln which I `feed the Vliock tothe brushes, to

be prepared. i i i This endless apron works on rollers, in

L, Fig. 2, passing around the pulley, M,`

e (which is on the end of one of the rollers,) `and the small pulley, or` extension ofthe varbor N, Fig. 2, which `arbor is `revolved by the band, O, workingon the pulley, N, F ig. l.` T, Fig.` l, is a loose roller which .merelyholds down the flock on the endless apron as itiis passing to the brush, E, Fig. 1.

The cylindrical brushes, D,E, andF, ,Fig l, are completely inclosed, to prevent `wasting the flock, by the sides ,of the spo'ut,

or conductor, A, and the cap, It, Fig. 2. And the whole machineis put in operation by means of the crank, S, or any other power i takes up the flock from the inner extremity of the endless apron, K, and carries it over to the brush, D, which runs with about onethird greater velocity, and strips the flock from the brush, E, and carries it down to t-he third brush, (indicated bythe pulley, F, Fig. 1,) which, (having a still greater velocity, indicated by the darts,) strips the flock from it and throws it down through the spout, or conductor, A, onto the endless apron B, or the web of wool as it is passing from the carding machine, as before described.

Should it be found Ithat the cylindrical brushes do not fully prepare the flock in every case, any greater number of brushes may be inserted by enlarging the space which they occupy in the frame.

All the brushes, except E, may be made of wire, or any other suitable material if it should be thought more convenient or useful, but the brush, E, which takes the flock from the inner extremity of the endless apron K, must be made of bristles, or some other soft and yielding substance, so that it will not injure the apron. I would recommend that this endless apron, (K,) be made of leather, though any other suitable material may be used with comparative advantage, when it can be kept sufficiently smooth.

Should it be necessary to use a narrower course of flock than the whole breadth of the apron, (K,) would convey, guides, made movable by sliding dowel'si, or by screws, may be used on each side, as seen at W, and W, Figs. l, and 2. And similar guides may be used in the spout, or conductor, for the same purpose.

The advantages of my improvement over all methods heretofore practised for making felting, consist in introducing the flock onto the web of wool in its passage from the cardy ing machine, (as while on the endless apron, 13,) so that, not only, the cards will not be clogged by passing the flock through them, but, also, the carding machine will card more than twice the quantity of wool, in the saine time, that it could if the flock passed through the machine with the wool. And the flock will be more thoroughly prepared by the additional machine, (before described,) than it wouldbe by passing it through the carding machine with the wool, and none of the shorter part of the flock will be wasted, as it always is when carded and running against the brush, D, as

with the wool, both by sticking in the cards, and by being thrown out by the operation of the machine. And in havin@ the preparing machine, (before described, wholly independent of the carding machine, so that it may be worked only when needed. So that the flock may be incorporated with that portion of the web of wool where it is desired, as extending throughout the whole texture, on one surface only, in the central part, so that both surfaces may be wholly of the web of wool, or in any other desired proportion either equal, or unequal. And as the carding machine will card more than twice the quantity of wool without the flock, and as the preparing machine is of small expense, the work can be done at much less ex-' pense than by any method heretofore practised, as well as doing the work better, and of any desired proportion of texture.

I am aware that flock has been incorporated with wool in the manufacture of fe1ting by passing it through the carding machine with the wool; and, also, that it has been pulled onto the surface of cloth during the process of finishing. I therefore do not claim either of these, as such, as my invention, but

What I claim as my invention, and desire to secure by Letters Patent, is

l. Preparing the web for felt fabrics by the introduction of layers of flocks between or upon the layers of wool without passing the flock through the carding machine, but by preparing it in a separate machine, and introducing it immediately from that machine onto the web of wool while it is passing from the carding machine, in the man ner, substantially, as herein described.

2. And I also claim as my invention the combination of the endless apron, (K,) which feeds the flock to the cylindrical brushes, with the series of cylindrical brushes, by which the flock is taken up from the inner extremity of the endless apron 100 and, (passing through the series,) is prepared and sent down through the spout, or conductor, (A,) and deposited on the web of wool, (as before described,) when the saine JAS.
